There is a phantom lurking in the forest. It is almost impossible to spot him, but his traces give him away. His footsteps in the snow tell us that he was heading towards the valley. The hole with the dry leaves was his ambush during the day. And the leftover of the prey shows what he was hunting for. As we follow his traces, we get to know the forest where he lives. We walk through river valleys, canyons, sunny crags and misty hills – this is the Northern Low Mountain Range, a transition zone between the Carpathians and the Great Plain, on the border of Hungary and Slovakia.
